Abstract
The invention provides a deflection yoke having two centering magnets mounted thereon for the adjustment of centering. Each of the centering magnets is molded in an annular form from a resin material containing a finely divided magnetic material, the centering magnet having two portions opposed to each other as displaced from each other by 180 degrees about a center axis of the annular form thereof and magnetized to an N pole and an S pole respectively, the content of the magnetic material varying circumferentially of the annular form, the distribution of the content being symmetrical about a straight line orthogonal to a straight line through a center point of the N pole and a center point of the S pole. The magnetic force for the adjustment of centering can be eliminated by the two magnets mounted in combination.
